DEVICE FOR SHARPENING KNIVES AND'ANALOGOUS ARTICLES.

SPECIFICATION forming part of Letters Patent No. 466,293, dated December29, 1891.

Application filed December 22, 1890. Seriallifo. 375,541- (No model.)

To all whom it may concern:

Be it known that I, J OHNA. PEER, of Book lyn, Kings co'unty, and Stateof New York, have invented a new and useful Improvement in Devices forSharpening Knives and Analogous Articles, of which the following is aspecification.

I will describe a sharpening device embodying my improvement, and thenpoint out'the novel features in the claims.

In the accompanying drawings, Figure 1 is a side view of a deviceembodying myimprovement. Fig. 2 is an end view thereof. Fig. 3 isaseetion taken diametrically through two disks which are comprisedin themachine. Fig. 4 is a view like Fig. 3, but the plane of the section isat right angles to that of Fig. 3.

Similar letters of reference designate corresponding parts in all thefigures.

A A designate two disks or carriers arranged adjacent to each other on arotary shaft A. This shaft is journaled in bearings 1) 17 formed in aframe B, which may be made of any suitable construction; but is hereshown as constructed so as to be capable of. being clamped to the edgeof a table or like device. affixed a pulley that receives a belt passingaround a driving-pulley b, rotating upon a stud b extending from thelower part of the frame B. The pulley b is provided with a crank bwhereby it may be rotated for the purpose of rapidly rotating the shaftA and its disks A A The disks A A are made of a composition comprisingemery and have projections a a on their opposite surfaces. Theseprojections 1 are shown as made in the form of radial ribs having theirfaces inclined'toward the shaft, and the projections of each disk areopposite the spaces between those ofthe other disk.

The disks are so arranged with relation to I each other that theinclined faces of the pro- On one end of the shaft A is forced downbetween the operative faces of the disks to any desired extent whichwill be desirable to enable it to be sharpened.

The disk A has a hub a which fits the shaft A, and is fastened thereonby means of a set-screw a This hub is formed integral with a metal pieceupon which the disk A is mounted. This metal piece comprises pairs ofjaws a that extend toward the other disk A The disk A is mounted upon ametal piece, which is in general construction similar to the metal pieceupon which the disk A is mounted; but it isloose on the shaft A. It Ihas ribs d, which fit between the pairs of jaws a The engagementof theribs a with the jaws a insure the rotation of the disk A with the disk Aand theshaft A. The ends of the jaws a form stops which limit themovement of the disk A toward the disk-A. One may be provided at its endwitha screw (1 and such a screw will form an adjustable stop, wherebyadjustments in the relation of the disks to compensate forwear can bemade. A wooden collar 0 surrounds the jaws a and ribs alto prevent theedge of a knife from reaching them and thereby sustaining injury.

The disk A is moved toward the disk A H by means of a helical spring 0'that is coiled around the shaft A between the hub of the disk A and anut D, that is fitted to a screwthreaded portion at the end of saidshaft. By adjusting the nut the tension of the spring may of course bevaried. On the insertion of a knife or like article between the disks 8the disk A may be moved away from the disk A against the resistance ofthe spring.

A honeholder E may be fastened to a bracket extending from the frame B.It is shown as made in the form of a trough pro- 0 vided with screws bwhereby a hone may be clamped in it.

What I claimas my invention, and desire to secure by Letters Patent, is

1. In a sharpener for knives and like articles, the combination of tworotary disks pro- .vided on their opposite sides with projections havinginclined faces and arranged so that those on one disk will be oppositethe spaces between those of the other disk, jaws extend- Ioo ing fromone disk, ribs extending from the other disk and engaging with the jaws,a m

tary shaft supporting the disk, means for se curing one of the disks tothe rotary shaft, and a spring for moving the other disk toward thatdisk which is fixed to the shaft, substantially as specified.

2. In a sharpener for knives and like articles, the combination of arotary shaft, disks or carriers mounted on said shaft to rotatetherewith and provided 011 their opposite faces with radial projectionshaving the front faces inclined toward the outer edge of the disks orcarriers and so disposed that the projections of each disk or carrierare opposite the spaces between the projections of the other disk orcarrier, one of said disks or carriers being mounted on said shaft so asto have a yielding movement lengthwise thereof", substantially asspecified.

In a sharpener for knives and like arti- JOHN A. PEER.
